Algebra-1

To factor the polynomial 4m² + 6mn + 4m + 6n, let's follow the factor by grouping method:

Step 1: Group the terms: (4m² + 6mn) + (4m + 6n)

Step 2: Factor out the common factor from each group:
In the first group, we can factor out 2m: 2m(2m + 3n).
In the second group, we can factor out 2: 2(2m + 3n).

Now, we have: 2m(2m + 3n) + 2(2m + 3n)

Step 3: Notice that (
